PAPER BAG.

SPECIFICATION forming part of Letters Patent N 0. 640,173, datedJanuary-2, 1900.

Application filed May 27,1899. Seria1No.'718,575. (N0 model.) I

To all whom it may concern.-

Be it known that I, LORENZO D. BENNER, a citizen of the UnitedStates,residing at Peoria, in the county of Peoria and State ofIllinois, have invented certain new and useful Improvements in PaperBags; and I do hereby declare that the following is a full, clear, andexact description of the invention, which will enable others skilled inthe art to which it appertains to make and use the same.

My invention relates to a new and novel construction of paper bags andthe method of making the same, the object being to form a satchel-bottombag collapsed into convenient form for shipment and readily expandibleinto a rectangular box-like form, the construction being such that inthe manufacture of the same the waste of paper will be reduced to aminimum.

The construction of the bag will be best understood from a descriptionof its mode of manufacture, in connection with the drawings, in which itis illustrated and in which the figures as they are numbered show intheir order the various steps of the method of producing the bag, inwhich- Figure 1 is a plan view showing the manner of cutting the tube orforming the same into convenient lengths. Fig. 2 is a view showing thesecond step in the process of manufacture. Fig. 3 is a plan showing afurther step in the process, wherein the side extensions are folded downupon themselves. Fig. 4 is a view showing the folds ofthe bagpreparatory to being brought together and pasted. Fig. 5 shows a bagcollapsed and as it appears when completed, and Fig. 6 is a View of thebottom as it appears when the bag is opened or filled.

In the drawings,A is a tubular section,made of suitable length, cut froma strip in such a manner as to provide the side extensions a. Inseparating the tube into suitable lengths, as is shown in Fig. 1, I formthe overlapping sections of the bottom by cutting the sides only, so asto form an arc of a circle, the end extensions a of one bag being cutout of the adjacent strip of tube or bag of which it forms a part, whichleaves at the opposite end of the 'bag the protruding end of the,bellows sides B, as is shown in Fig. 1.

The first step in the operation is to grip the extensions a and foldthem back upon themselves on the line a, which will form a crease in thebellows sides B on the diagonal lines I), forming the crease b, whichforms a triangular fold Z) of the sides a upon itself, the process offolding providing the triangular extensions 0, which represent the foldsof the bellows sides folded down upon themselves. The extensions a arepurposed to be folded back on the lines c 0 so that when they arebrought together (the operation of which is well illustrated in Fig. 4)they may be overlapped upon each other or folded back and then broughttogether and pasted. Figs. 5 and 6 illustrate the manner in which Iprefer to paste the side extensions together, wherein the end of oneside (which may be either of the folds folded back on the lines 0' 0 isfolded back against itself as ,the sides are brought together and theopposite side is caused to overlap the same and pasted down.

In the process of pasting the extensions a it may be found desirable toperforate the triangular fold b or cut the same away when severing thetube preparatory to folding the same, which would enable me' to securethe triangular extensions 0 to the outside lengths of the bag. This isnot really necessary; but in the construction of the bagI do not wish tolimit myself to the exact manner of retaining the parts together, as isshown in the drawings.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is- I 1. The method of making a bellows-foldedsatchel-bottom bag, which consists in severing the length of a bag froma plain tube in such a manner as to provide extended side portions fromone end and protruding bellows-side extensions from the opposite end,folding the extensions back upon themselves forming triangular sideextensions in the bellows sides, redoubling the extensions over thetriangular extensions and folding the ends of the side extensions insuch a manner as to complete the bag by forming overlapping ends whenpasted down.

2. The described method of making a pa per bag, which consists informing a blank as to provide extended side portions at one end andprotruding bellows sides at the opposite end, folding the extensionsback upon themselves on the line a, forming the triangular bellows-sidesextensions 0, causing the extensions to be redoubled upon themselvesforming the triangular folds b b folding back the extensions a, as tooverlap the extensions c, so as to bring the inner matching faces of thesides a, adjacent to each other and completing the bag by folding eitherof the end extensions a, and overlapping the 0pextended side portions a,a, from an extended tube and folding the same back on the line a, a, theiuturned bellows-sided portions 0, the overlapping portions b,contiguous therewith, and the matching and overlapping end extensions ofthe sides a, when pasted down completing the bottom of the bag.

5. The herein-described bag provided with the side extensions a, havingprotruding ends which are purposed to extend beyond and overlap theinturned portions 0, and the overlapping portions b, of the bellowssides, in such a manner as to complete the bag by forming overlappingends when pasted down.

In testimony whereof I aflix my signature in presence of two witnesses.

LORENZO D. BENNER.
